 ===============
 
 
+v0.17 (2019/09/22)
+------------------
+
+*  Pygments syntax highlighting for the Python console (``pycon`` lexer) now
+   uses the ``python3`` option, and the default Python lexer is now
+   ``python3`` (#156).
+
+*  Added support for JavaScript (#147; thanks to Nathan Carter).
+
+*  Updated Julia support for Julia versions 0.6 (#107), and 0.7 and 1.0 (#126,
+   #130).
+
+*  There are now meaningful error messages for the Julia console when Weave.jl
+   is not installed or raises errors (#131).
+
+*  ``pythontexcustomcode`` and ``\pythontexcustomc`` now set
+   ``pytex.context`` (#65).
+
+*  Added support for R.  The ``R`` family of commands and environments
+   (``\R``, ``\Rc``, ``Rcode``, ...) executes code as a script.
+   There is currently no utilities class or equivalent.  The ``Rcon`` family
+   (``Rconsole``) executes code to emulate an interactive R session (#121).
+
+*  ``fancyvrb`` settings from ``\setpythontexfv`` and console
+   environments now work with Julia and R consoles.
+
+*  ``pythontexcustomcode`` now works with ``juliacon``.  There are now proper
+   ``juliaconcode`` and ``Rconcode`` environments that execute code but
+   typeset nothing, to parallel ``pyconcode`` (#134).
+
+*  Added support for Perl with the ``perl`` and ``pl`` families of commands
+   and environments.  There is currently no utilities class or equivalent.
+
+*  Added support for Perl 6 with the ``perlsix`` and ``psix`` families of
+   commands and environments (#104).  There is currently no utilities class or
+   equivalent.
+
+*  Updated Rust support by using ``dyn`` with traits in utilities object.
+
+*  Under Windows, capitalization of script paths in ``stderr`` is now
+   preserved.
+
+*  Fixed a bug that prevented the ``sub`` environment from working with
+   ``depythontex`` (#155).
+
+*  Fixed a bug in checking mtime of dependencies to see if they have been
+   modified while ``pythontex`` is running.  The check failed for dependencies
+   that do not exist or were deleted before ``pythontex`` can read them
+   (#136).

+% \begin{itemize}
+% \item Pygments syntax highlighting for the Python console (\texttt{pycon} lexer) now uses the \texttt{python3} option, and the default Python lexer is now \texttt{python3} (\#156).
+% \item Added support for JavaScript (\#147; thanks to Nathan Carter).
+% \item Updated Julia support for Julia versions 0.6 (\#107), and 0.7 and 1.0 (\#126, \#130).
+% \item There are now meaningful error messages for the Julia console when Weave.jl is not installed or raises errors (\#131).
+% \item \texttt{pythontexcustomcode} and \texttt{\string\pythontexcustomc} now set \texttt{pytex.context} (\#65).
+% \item Added support for R.  The \texttt{R} family of commands and environments (\texttt{\string\R}, \texttt{\string\Rc}, \texttt{Rcode}, ...) executes code as a script.  There is currently no utilities class or equivalent.  The \texttt{Rcon} family (\texttt{Rconsole}) executes code to emulate an interactive R session (\#121).
+% \item \texttt{fancyvrb} settings from \texttt{\string\setpythontexfv} and console environments now work with Julia and R consoles.
+% \item \texttt{pythontexcustomcode} now works with \texttt{juliacon}.  There are now proper \texttt{juliaconcode} and \texttt{Rconcode} environments that execute code but typeset nothing, to parallel \texttt{pyconcode} (\#134).
+% \item Added support for Perl with the \texttt{perl} and \texttt{pl} families of commands and environments.  There is currently no utilities class or equivalent.
+% \item Added support for Perl 6 with the \texttt{perlsix} and \texttt{psix} families of commands and environments (\#104).  There is currently no utilities class or equivalent.
+% \item Updated Rust support by using \texttt{dyn} with traits in utilities object.
+% \item Under Windows, capitalization of script paths in \texttt{stderr} is now preserved.
+% \item Fixed a bug that prevented the \texttt{sub} environment from working with \texttt{depythontex} (\#155).
+% \item Fixed a bug in checking mtime of dependencies to see if they have been modified while \texttt{pythontex} is running.  The check failed for dependencies that do not exist or were deleted before \texttt{pythontex} can read them (\#136).

 % \section{Support for additional languages}
 % \label{sec:other-languages}
 %
-% Beginning with v0.12, it is much simpler to add support for languages beyond Python.  Support for several additional languages will be added in coming months.
+% Details about adding support for additional languages are in \Cref{sec:other-languages:adding}.  This section begins with a brief overview of supported languages and available features.
 %
-% In the immediate future, support for additional languages will be part of \pytex.  Later, it may make sense to provide an alternative interface for other languages.  For example, a package could be created that provides access to \pytex\ internals in a language-agnostic manner, without having the word ``python'' as part of the command names.
-%
-% Languages beyond Python will typically not be enabled by default, to prevent potential macro naming conflicts with other packages.  At least two possible base names for commands and environments will be provided for each language.  Typically these will be the name of the language and the language's file extension.  For example, Ruby has the |ruby| and |rb| base names.  You can choose which base name to use for creating a family of commands and environments based on personal preference and potential naming conflicts.
+% Languages beyond Python are typically not be enabled by default to prevent potential macro naming conflicts with other packages.  Languages are enabled via the |usefamily| package option (\Cref{sec:usage}).  For example,

-% Preliminary Julia console support was added in v0.16, under the base name |juliacon|.  Unlike the Python console environments that allow invalid input, currently everything entered in a |juliaconsole| environment must be valid.  The Julia console uses \href{https://github.com/mpastell/Weave.jl}{\textsf{Weave.jl}} internally to evaluate code, and it currently does not support invalid input.

+%
+% Support for R was added in v0.17.
+%
+% Loading \pytex\ with |usefamily=R| enables the |R| family of commands and environments (|\R|, |\Rc|, |Rcode|, ...).  These execute code with |Rscript|.  The |methods| library is loaded automatically as part of the template code.  Expressions passed to the |\R| command are converted into strings via |toString()|.  There is currently no utilities class or related features.  A null graphics device, |pdf(file=NULL)|, is created by default to avoid the automatic, unintentional creation of plot files with default names.  Plots that are to be saved require explicit graphics commands.

+% Loading \pytex\ with |usefamily=Rcon| enables the |Rconsole| environment, which executes code to emulate an interactive R session.  There is also an |Rconcode| environment that executes code but typesets nothing.  Code is executed with |Rscript|.  The |methods| library is loaded automatically as part of the template code.  The option |echo=TRUE| is used to intersperse code with output, while |error=function(){}| is used to avoid halting on errors.

 %
 % Adding support for an additional language involves creating two templates,  creating a new instance of a class, and using a \pytex\ macro.  In some cases, additional changes may be necessary for full support.  The information below does not deal with creating |console| families; additional support for user-defined |console| families will be added in the future.

The default |fancyvrb| macro needs an argument to tell it the name of the file to which to save the verbatim content.
